OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH10PA060000ALAA

This is the factory-authorized OEM replacement control transformer for the Carrier PH10PA060000ALAA packaged heat pump unit. Part number HT01AW229 steps down line voltage (115, 208, or 230V primary) to a safe 24V AC secondary to power the control board, thermostat circuit, and all low-voltage safety and switching components. When this transformer fails, the entire control circuit loses power — the thermostat goes blank, the system will not respond to any call for heating or cooling, and contactors or relays will not energize. Replacing the transformer is one of the first diagnostic steps when an HVAC system appears completely dead with no low-voltage signal.

• Specs: 60 VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount chassis | OEM part number HT01AW229 / HT01AW229A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact VA rating and insulation class tolerances. Off-brand transformers frequently underperform at 60VA load, causing nuisance tripping of the secondary fuse and premature control board failure.
• Install difficulty: 3/5 — Disconnect power at the disconnect and verify voltage is absent with a multimeter before touching any wiring. Label all primary and secondary leads before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire nuts or terminal connectors. Verify correct primary tap (115V, 208V, or 230V) matches your supply voltage before energizing.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.
